So they hire tons of engineers who have nothing to do but rearchitecture the mess their microservices have created.
Then there are others who create observability and test harnesses for all of that.
When Pornhub and other porn sites can deliver orders of magnitude more data across the world with much simpler systems, you know it's all bullshit.
In the time since those problems have been solved and now are offered as a service by most cloud providers (for a hefty fee of course)
When is that, exactly? https://www.statista.com/chart/15692/distribution-of-global-...
Just one of the questions I have regarding this -- China has nearly 1.4 billion people, and barely any of them use any of the services here. Instead, they have their own video platforms. And you tell me that none of those platforms use at least the same amount of traffic of Prime Video? I doubt it.

That's nothing. My dedicated server delivers two orders of magnitude greater traffic than Pornhub (and everything in the Mindgeek network really). And I don't even need the cloud. Just better engineering.
